CLOTH ES-WRINGER.

SPECIFICATION forming part of Letters Patent No. 450,080, dated April 7,1 891.

Application filed December 19, 1390. Serial No. 375,195- (No model.)

To all whom it may concern:

Be it known that I, MELVIN NEWTON Lov- ELL, a citizen of the UnitedStates, residing at Erie, in the county of Erie and State ofPennsylvania, have invented certain new and useful Improvements inOlothes-Wringers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such aswill enable othersskilled in the art to which it appertains to make .and use the same.

This invention relates to clothes-wringing machines, and particularly tothat type of clothes-wringers in which the expressing-rolls are heldwithin the ends of C-formed springs, which give to the rolls theirexpressing-power; and it consists in certain improvements in theconstruction thereof, as will be hereinafter fully set forth, andpointed out in the claims.

The object of the invention is to provide clothes-wringers of the typeherein named with anti-friction roller-bearings.

In the accompanying drawings my invention is illustrated as follows:

Figure 1. is an elevation View of one end of a clothes-wringer of thetype above named with myimprovements thereon. Fig. 2 is averticalsection view taken on the line as w' in Fig. 1.

In the type of clothes-wringer shown, as commonly constructed, when thesprings are made of steel, so far as I am aware, the journal-bearings ofthe roll-shafts are formed on the ends of the springs by forging thereona half-box, in which the roll-shafts lie. The construction and finishare crude, and the machines when in use run very hard, and the wear onthe journals is great. I obviate these ojections by providing thejournals with antifriction bearings; but in order to adapt such machineto receive and retain such bearings certain new and improved details ofconstruction are required, and these constitute the essence of myinvention. The construction shown in the accompanying drawings is asfollows:

A A are roll-shafts; A A, the rolls; B, a metal shield, and C thesprings. These parts are made substantially as in all wringers of thistype, except a peculiar formation given to the spring at its ends toform a seat 0 for holding the roller-bearing case in place.

The anti-friction roller-bearings consist of a cylindrical case D, withfixed end rings F and rollers E. The cylindrical case D is made ofcommon tubing properly finished on the inside to form a surface for therollers E and seats for the end rings, which are held in place byturning the ends of the case down over them. The ends of the springs Care formed with sufficiently large curves to form proper seats 0 toreceive the roller-bearing cases, and, if desired, there is formed onthe edges of the seats 0 flanges c to hold the bearing-cases fromlongitudinal movement.

The frictional contact of the outer surface of the cylinder D and theinner surface of the seats 0' on the spring ends prevent thebearing-cases from turning ordinarily; but by prying the spring apartenough to loosen the bearings, they can be turned so as to change thepoint of greatest wear when desired.

I am aware of the construction shown in Letters Patent No. 275,165,granted to J. E. Donovan, in which anti-friction roller-bearings areapplied to a clothes wringer having C-formed springs formed of wood,andI therefore do not claim, broadly, the application of such bearingsto such wringers; but it will be observed that the Donovan device does,
